BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to a rocking exercise apparatus for giving exercise loads to a user by letting a seat make rocking movements with the user seated on the seat. [0003] 2. Description of the Related Art [0004] Rocking exercise apparatuses for giving exercise loads to users by letting seats make rocking movements with the users seated on the seats as above have been spread from health or fitness clubs where these apparatuses have been initially used to general households as convenient exercise apparatuses usable from children to the old. Typical prior arts of such rocking exercise apparatuses are disclosed, for example, in Japanese Examined Patent Publication No. H06-65350 and Japanese Unexamined Patent Publication No. 2004-216072. [0005] The technology disclosed in Japanese Examined Patent Publication No. H06-65350 relates to a training apparatus for preventing low back pain by realizing a series of rocking patterns using a 6-axis parallel mechanism. [0006] The technology disclosed in Japanese Unexamined Patent Publication No. 2004-216072 relates to a balance training apparatus which realizes three kinds of movements including reciprocating linear movements of a seat along longitudinal direction, reciprocating pivotal movements thereof about a longitudinal axis and reciprocating pivotal movements thereof about a transverse axis by a compact driving apparatus. [0007] However, since six driving sources are provided and separately controlled according to the technology of Japanese Examined Patent Publication No. H06-65350, the operation timings, speeds, operation ranges of the respective driving sources are separately controlled, therefore a fairly complicated control is necessary. Further, since six driving sources are provided, there are additional problems that the apparatus tends to be enlarged and production cost is high. [0008] Further, since the seat can make only three kinds of movements including reciprocating linear movements of the seat along longitudinal direction, reciprocating pivotal movements thereof about the longitudinal axis and reciprocating pivotal movements thereof about the transverse axis according to the technology of Japanese Unexamined Patent Publication No. 2004-216072, the movements become monotonous. Thus, there is a demand for improvement to obtain a larger fitness effect. SUMMARY OF THE INVENTION [0009] An object of the present invention is to provide a rocking exercise apparatus which can perform complicated movements to give a larger fitness effect while being small in size and inexpensive. [0010] According to an aspect of the present invention, a rocking exercise apparatus is provided with a driving source and a rocking mechanism for translating a torque of an output rotary shaft of the driving source into rocking movements of a seat seated by a user. The rocking mechanism includes: a first supporter for supporting a movable mount provided on a base such that the movable mount can make reciprocating pivotal movements about a longitudinal axis, a second supporter for supporting a pedestal fixedly attached to the seat such that the pedestal can make reciprocating pivotal movements about a transverse shaft provided in the movable mount via a connection link, a first translating mechanism for translating the rotary motion of the output rotary shaft of the driving source into reciprocating linear movements of the pedestal along longitudinal direction and reciprocating pivotal movements of the pedestal about a transverse axis via the second supporter, a second translating mechanism for translating the rotary motion of the output rotary shaft of the driving source into reciprocating pivotal movements of the pedestal about the longitudinal axis via the first supporter, and a changer for changing the movement condition of the reciprocating pivotal movement of at least one of the first supporter and the second supporter. [0011] These and other objects, features, aspects and advantages of the present invention will become more apparent upon a reading of the following detailed description and accompanying drawings.
